Just as the world is enchanted and intrigued about Meghan Markle, the public were once mesmerised by Hollywood silver-screen star Grace Kelly. Also an American actress, Grace Kelly left the world of acting behind to marry her love, Prince Rainier of Monaco.

Meghan’s life appears to be following a similar pattern to Grace Kelly’s, as the 35-year-old appears to be set to leave her acting career behind in order to marry into the the royal family. After just under one year of dating Harry, Meghan has already shut down her lifestyle blog ‘The Tig’, and rumour has it, she has asked to be written out of smash-hit series ‘Suits’, which originally propelled her to fame when she won the role of ‘Rachel’ in the drama.

As Meghan and Harry’s relationship builds from strength to strength, one royal has some words of warning for the US actress before she decides to marry Prince Harry, and rushes in to joining the royal family

Son of Grace Kelly and heir to the Monaco throne, Prince Albert of Monaco shared his advice for Meghan Markle, as she sets off on a path very similar to his mother’s. The Prince told People in the US, “The only kind of advice I can offer is the British expression: ‘Keep calm and carry on’ ”.

Talking about marrying into a royal family Prince Albert admitted, “it is a pretty tough act.”

“Especially in the British royal family, which is scrutinised by the press as no one’s been.”

Although he said that the couple “seem to be having a good deal of success so far” he warned that Meghan should be prepared, “to face the full onslaught” of the press and public attention if she is ready to make the ultimate commitment and marry Prince Harry.

“Being an actress, in a way, gets you a little prepared but nothing really can prepare you for the constant pace of it. Particularly now that the pace has changed so much. It’s hard for anyone to handle,” he added.

Speaking of how his own wife, Princess Charlene, dealt with the attention after joining the royal family following a successful Olympic swimming career Albert revealed, “It was difficult for Charlene to handle. I can’t imagine the difference now with the increased pace of news and social media.”

Passing on some words of wisdom from his late mother Grace Kelly Albert concluded, “Mum taught us that you have to do all you can to protect your private life.”

“But you also have to face the press at some points. When we went on family holidays together, we would take an hour on the first morning and give that to the photographers. We let them have that hour and in return they would let us go on with our lives during the vacation.”

This approach to the press is something that Prince William and Kate have handled well. Sharing intimate family photos with the public of their holidays or Prince George and Princess Charlotte pictures to mark each birthday, Prince Harry’s older brother is careful to keep the press at a distance, whilst also accepting the public’s interest in his wife and his children.
